Carbon dioxide emissions in the United States fell again in 2015, according to new data from the federal government. Though the levels increased slightly in 2013 and 2014, last year’s drop is in line with the gradual decline that’s been occurring for a decade. The nearly 5.3 billion metric tons of energy-related carbon dioxide the country added to the atmosphere in 2015 is 12 percent smaller than that number in 2005.
And not due to recessions either:
More recently, however, the U.S. economy has continued to grow even in years that have seen decreases in emissions. In 2015 the economy was 15 percent larger than in 2005, but the country emitted 23 percent less carbon dioxide per dollar of GDP last year compared with 10 years prior.
This is the challenge – to reduce emissions without reducing GDP.
In the U.S., the decoupling of emissions from economic growth was largely a result of the boom in domestic gas production thanks to hydraulic fracturing. And while the deployment of renewable energy technologies has also increased substantially of late, burning natural gas instead of coal for electricity will likely continue to be the main contributor to emissions declines for years to come.
Yet the Greens oppose fracking despite saying reducing CO2 emissions is critical to our survival. Which is it? Can’t have it both ways.
